ABSTRACT:
A locking device for securing a component, such as a seating frame to a floor, for example, in an aircraft, includes a locking bolt, one end of which is provided with a locking cross-head, having two projections that engage under rail rims of a support rail in the floor. The other end of the bolt is provided with a threading that cooperates with a nut for providing the required clamping force. At least two alignment guide studs are so positioned that the locking bolt is oriented intermediate the two studs. These studs fit into respective recesses in the rail for properly locating the locking device. A carrier member of the locking device may be a separate base plate or it my be part of the seating frame structure. A slot, at the visible end of the locking bolt, is so oriented, that it indicates the locked or unlocked condition of the locking bolt. The slot also serves for inserting a tool to bring the cross-head with its projections into the locked position and to then hold the bolt for tightening or loosening the nut.
